heavy metal concentrations in molluscs from the atlantic coast of southern spain.trace metals were determined in the two most abundant species of bivalve molluscs along the atlantic coast of southern spain (donax trunculus and chamelea gallina) and in the sediments where they live. the results show that the area near the mouth of the huelva estuary is where the highest metal concentrations are found in sediments and in the two bivalve species. this is not surprising, considering that the huelva estuary is the mouth of the tinto and odiel rivers, which have one of the highest ...200515833492
organochlorine compounds (pcbs, pcdds and pcdfs) in seafish and seafood from the spanish atlantic southwest coast.concentrations and congener specific profiles of pcdd/fs and pcbs were determined in edible fish and seafood species from the coast of huelva, in the spanish southwest atlantic coast. five fish species, namely wegde sole (dicologoglossa cuneata), common sole (solea vulgaris), white seabream (diplodus sargus), sardine (sardina pilchardus), angler fish (lophius piscatorius), two shellfish species (donax trunculus and chamelea gallina), common cuttlefish (sepia officinalis) and prawns (parapenaeus ...200616483635
is delta-aminolevulinic acid dehydratase activity in bivalves from south-west iberian peninsula a good biomarker of lead exposure?the coast of huelva is considered as a heavily contaminated area where the tinto and odiel rivers discharge after running through a metalliferous mining area in the iberian pyrite belt and end in common estuary called ría of huelva. lead is a highly toxic and widely distributed element in the aquatic environment; therefore there is a great interest in assessing the impact of this contaminant on aquatic organisms. to study the bioavailability and sources of lead, the bivalve species chamelea gall ...200818381224
